Wherein: described support arm is " L " type, two ends all have " U " type groove, on support arm, have bar hole near the position of support arm one end, and the other end of described screw rod is passed by this bar hole; On described support arm, be positioned at bar hole contiguous block be installed, this contiguous block is connected with support arm by the second bearing pin, the other end of described screw rod is passed by contiguous block; The level interval of described squeegee roller and soldering set is 1～5mm, and on the minimum point of squeegee roller and soldering set the shaft shoulder in same level; The diameter of described squeegee roller is 30～60mm, and thickness is more than or equal to the diameter of the shaft shoulder on soldering set; The extruding force that described squeegee roller applies welded piece moves downward realization by main shaft, and the extruding force applying is 1～3KN.
The present invention with weldering pressurizing unit with weldering pressing method, comprise the following steps:
Step 4, restarts friction stir welding machine, and main shaft again rotates and drives soldering set to move and weld along welding direction with the feed speed of setting, and forms weld seam; In this process, the squeegee roller that welded piece has been applied to predetermined compression power carries out synchronizing moving along welding direction above soldering set, play friction stir welding process with weldering squeezing action.
Wherein: in the process of friction stir welding, the both sides of the edge of described welded piece are pushed spacing by jig to welded piece; Described welded piece be similar or foreign peoples can be soldered sheet metal, welded piece can dock or overlap.
Advantage of the present invention and good effect are:
1. when the present invention is with the larger or less sheet metal of weldering pressurizing unit weld width, can effectively reduce the manufacturing cost of jig, simplify the process that is installed before weldering, increase the welding space of soldering set, thereby the high-quality that has ensured weld seam is shaped and has widened the range of application of agitating friction welding technology.
2. with weldering, the support arm in pressurizing unit is designed to " L " type in the present invention, ensured level interval less between squeegee roller and soldering set, strengthened squeegee roller in welding to welded piece with weldering squeezing effect.
3. when the present invention carries out friction stir welding with weldering pressing method to the larger or less sheet metal of width, only need to adopt jig it to be pushed spacing at sheet edge, and without the rigidity squeezing action of jig is applied near axis of a weld, can ensure soldering set in friction stir welding process through the close contact of position welded piece and backing plate at bottom, the high-quality that realizes welded piece connects; This had both reduced the design and manufacture cost of jig, had simplified again the process that is installed before weldering, had also enlarged markedly the welding space of soldering set simultaneously, had widened the range of application of agitating friction welding technology.
